Abstract

In known sheet-fed rotary printing machines, a sheet is lifted from the first impression cylinder at its trailing edge by a suction gripper system arranged on a sheet transfer cylinder and is transferred to mechanical grippers likewise arranged on the sheet transfer cylinder, whereas the leading edge of the sheet is held on the first impression cylinder by a mechanical gripper system. Since the gearing which actuates the suction grippers is intended expressly to avoid a relative movement of the sheet, it is not possible to stretch out any folds or bulging which may occur. According to the invention, a circumferential component counter to the direction of rotation of the sheet transfer cylinder is imparted to the suction heads (14), arranged on the suction gripper system (11), during the return movement by the gearing (16, 18) driving them. As a result, the suction heads (14) slide along in the rear part of a sheet (8) in the direction of its trailing edge and make the sheet (8) taut before it is transferred to the mechanical gripper system. <IMAGE>
